I just became a Star Wars fan several months ago. I watched them in the numbered order, that's 1, 2, 3, 4, 5, and 6.
Besides that, the 2004 SE was the first vesions of the OT I saw, so I have different view on it. But I'm sure that I'd be pretty pissed if I grew up watching a perfect movie and then in the future they completely screw it up.
Even though I've only seen the SE of the OT, after reading about all of this I see what problems the changes I saw were.
Reaction to certain scenes:
A New Hope:
"Your father wanted you to have this when you were old enough": Anakin didn't even know he had a son...
Jabba/Han scene: I imagined Han's boss to be a bit...different
Luke's falcon training: Isn't he supposed to have a blue lightsaber?
Obi-Wan vs Darth Vader: Wonder why Obi-Wan calls him, "Darth"...
Empire Strikes Back:
Luke & Leia kiss: Wait, didn't Padme name her babies Luke & Leia?
Yoda's appearance: Did...is Yoda on drugs or something? And his voice got...heavier
Cloud City entrance: I seriously doubt that this scene was in the original version...
Vader/Emperor scene: Palpatine looks exactly the same as he did in Episode III. Don't people age?
"I am your father": I already suspected this in either one of the movies since it's probably the most heard quote
Return Of The Jedi:
Jabba's appearance: *just realizes that Episode I had Jabba* Alright, Episode IV CG Jabba officially sucks. This is much better.
Leia says she remembers her mother: BULL. SHIT.
Palpatine's appearance: He looks like he lost weight compared to Episode III & V...
Unmasking scene: If Anakin was burned, why does he only have burn marks on the side of his cheek?
Anakin/Obi-Wan/Yoda final scene: Why is Anakin just looking around everywhere?
My dad's reaction to the final scene: Who's that guy on the left?
Now typing this out helps me see why the PT kinda ruined the OT.
